Uniaxial : Set freely within ±1°~±180° (deg)
e.g. -90˚ ~ +90˚ or -30˚ ~ +60˚

Uniaxial 360 : 0°~360°

For 2-axis specifications, individual measurement ranges can be specified for each axis.
For the 2-axis ±90° (deg) specification, the error range increases at angles exceeding ±85° (deg).

The minimum/maximum angle must satisfy each axis' designated range.
Please inquire separately for less than -3° ~ +3° (deg)

Apply RS485 own protocol.

Wiring Connections

Axial	Color	Analog	RS485
Uniaxial	RED	V+
	Black	GND (COM)
	GREEN	X+	A (T+)
Biaxial	WHITE	Y+	B (T-)

MSENS series is wired by MG610331-5 plug (Korea Electric Terminal Co., Ltd.). The plug can be deleted or wired with MG64REC (separately sold) according to specifications.

RS485 output has always 4C connections.

Analog Data Descriptions

Deg. from Analog - Vdc output
- Measuring Range = max range - min range
- Output V Range
  = 4.5V - 0.5V = 4V
- Zero Offset = 2.5V
e.g. Measuring range +/-90 deg, Output 3.5V,

Deg. from Analog - mA output
- Output mA Range
  = 19.68mA - 4.32mA = 15.36mA
- Zero Offset = 12mA

②	Output	MV MA 485	0.5 ~ 4.5Vdc 4.32 ~ 19.68mA (Uniaxial only) RS485
③	Range	Set measuring range
④	Attachment Direction	F W	Floor Mount Wall Mount
⑤	Rotational Direction	CW CCW	Clockwise (default) Counter-clockwise

Code format : MSENS-IN- [①]-[②]-[③]-[④]-[⑤]
e.g. MSENS-IN-S-MV-90-F-CW

Optional
- Receptacle P/N : MG64REC
- To extend the length of the sensor cable, an additional cable with opposite connectors must be ordered.

RS485 Protocol

Communication Standards

Baudrate	9,600	Data Bits	8
Stop Bits	1	Parity	None

Data Format (ASCII)
= STX + Xdeg + SP + Ydeg + ETB + Check Sum + $
- [SP+Ydeg] is skipped for Uniaxial.
- Check Sum : Substitute ASCII of each bytes for HEX and calculate by XOR.

Commands (not case sensitive)
Carriage Return and Line Feed must be attached to end of commands.
e.g. #DATA+CR+LF

#DATA	Measure data once.
#READ	Measure data continuously.
#STOP	Stop measuring.
#INFO	Get sensor information.
#ID{NO}	Set ID to {NO}.
#SAVE	Save settings

ID can be set within 0~80. (in HEX, plus B0 to ID : B0~FF)

To complete ID set, set ID on ID set mode, power off and on again.

Multiple sensors on parallel connection, can measure individual sensor data ; set individual sensor ID and send below command in HEX.
CR+LF is unnecessary in this case.

Command : Sensor ID [B0~FF] + 05
e.g. (HEX) B1 05

Notes

Specification changes after shipment will be charged for a fee, so be sure to order with the correct specifications.

Ground connection is recommended in noise occurred environment.

MEMS based inclinometer (tilt sensor) measure tilt (degree) by gravity. Check sensing directions before use.

Check wiring connections before use.

12 months warranty is provided after released. Warranty provided only in case of using for designed purpose correctly.

Specifications, design and components can be changed without prior notice to improve its performances.
